The combination in a locomotive, of the cross-head, a connecting-rod G, a doubleforked lever F pivoted to the frame of the 10- comotive, drivingaxles, cranks therefor, a yoked parallel rod connected to the cranks of the Wheels, an intermediate rod I coupled to the lever F and to the rod within the yoke, the end of one arm of the lever also extending within the yoke, substantially as described.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
